PROCESS OF MAKING PLASTIC CO SPECIFICATION forming part Of Letters Patent NO 469,111,!ate Februaz 16, i Application filed February 24, 1891. Renewed December 12,

To all whom it may concern;

Be it known that I, JOSEPH H. AMIEs, a citizen of the United States, and a resident of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvemcntsin Processes of Making Plastic Compositions; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referenee being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in processes for making plastic compounds or compositions.

The ob ect of the invention is to provide a noifel process for making plastic compounds which may be advantageously employed as a substitute for lumber, siding, flooring, roofing, beams, columns, and for manufacturing railroad ties or sleepers, as well as for building-stone,tiling, paving, and for many other useful purposes; and with this object in View the invention consists in the novel process which will be hereinafter fully described, and specifically defined in the claim.

In carrying my invention into effect I take a tank of any suitable dimensions and shape and partly fill the same with water. I then add to the water a suificient quantity of long fibrous tentacles of hem 'ute or other similar material. A quiveriw otion is then given to the tariIiTwhieh-wiihifi'found to have the effect of loosely weaving or intermingling the fibers or matting them together. I then add asufiicient quantity of finelypoullggaih dr eor theltsnitabl cement we! t ie ma e ers,a er w 110 I add a filling oranysunabie'e'lastic scrap or waste-such as small ieces of wood sawdust or a r cumn' s or ar 111% 1e qulveringaction or motion of the mixing tank or vessel still being maintained. The mass will now assume a pglpy character and is in condition to be trans erre sui able molds or dies, in which it is subjected to pressure, whereby the water is expelled and a compact spongy body obtained, which when dry may PATENT OF ICE.

be advantageously employed for the purposes hereinbefore enumerated, as nails or spikes can be readily driven therein and will be tenaciously held thereby.

The proportions of the substances used should be about fifty per cent, in bulk, of

fiber, twenty-five per cent. cement, and twenty-five percent. of filling material, with sufiicieut water to form a plastic or pulpy mass when all of the ingredients shall have been incorporated. It will be obvious, however, that thescproportionsmey e varied according to circumstances and the nature of the compound or composition to be produced- It is neces ary that-the fibers should be what are known as lgnglijlgers the longer the better, so that they will be interwoven or intermingled, so as to mat together when subjected to uie qnwsni action while suspended in the water in the tank. Thea nountpt cement usedmust be sufiicient to exclude moisture and avoid swellingand maintain the spongy nature of the product, so as to tenaciously hold nails, screws, or spikes. This may he regulated by adjusting the amountof pressure to which the mass is subjected and properly proportioning the amount of filling material and cements contained therein.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The hereinbet'ore-described process of producing plastic compounds or compositions, the same consisting in subjecting long fibrous tentacles to a ,guivering action while suspended in water jifa ffsTiit'ablei vessel, .then adding thereto a suitable cement, next adding a filling of elastic waste, o 1 ;,s crap., the quivering action still being maintained, and finally subjecting this mass to pressure to compact the same and expel the water, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto afiixed my signature in presence of two witnesses.
